2 Claims. 1

This invention relates to chairs, and more particularly chairs of the typewriter character or type.

The primary object of the invention is to provide a chair which minimizes the use of metal.

The invention further aims to provide a chair constructed principally or mainly of Wood, and which at the same time preserves all of the characteristics and functions of chairs of former constructions involving the use of considerable metal.

The invention has for a further objective to provide a chair which is of sturdy and rugged construction.

A still further objective of the invention is to provide a chair the base of which is of compact construction and which also adheres in appearance to chairs of prior manufacture.

Still further the invention aims to provide an improved means for rotatably mounting the seat which dispenses with the use of metal and which still enables free rotation of the seat.

The invention has still other and further objects which will be later set forth and of them-.- selves mainfested in the course of the following description.

In the drawings:

Figure 1 is a side elevation of the invention,

showing the back in one of its adjusted positions in dotted lines.

Figure 2 is a section on line 2-2 of Figure 4.

Figure 3 is a front elevation with the base omitted.

Figure 4 is a bottom plan view of the seat structure, and

Figure 5 is a bottom plan view of the base.

In proceeding in accordance with the present invention, a base is provided having wood legs I which are secured to and radially extend from a central wood hub 2 having a flanged upper end 3 with which the upper portions of the legs abut. A spider d, formed of fibrous material is secured to the legs by means of screws 5, as more clearly depicted in Figure 5.

A wood seat has a supporting block 'I secured to and depending from its under face and which latter is also formed of wood. The block has a bore 8 which extends through its bottom, to a point spaced from its top whereby to form an end wall or bearing 9 for a ball I0, which may be formed of marble, glass or wood, or other material, and whereby the seat is mounted for free rotation. The diametrically opposed portion of the ball is seated upon the upper end I I, of a wood post I2, carried by the base.

To hold the post against upward movement, a

2 pin I3 is driven through block 'I and engages in a circular groove I 3 formed in the upper end of the post.

The postA I2 extends within the hub 2, o f the base and vis forrm'edl with a series of spaced openings I4, in a selected one of which is received a removable pin I5 carried by the base and by means of which the seat carried by the post can be disposed at varying elevations most comfortable to or in accordance with the needs of the user or occupant.

The back I6, likewise of Wood, has a pair of horizontal Wood arms I'I rigidly attached thereto and which engage the outer faces of arms I8. The arms I 8 have their inner faces fixedly secured to the adjacent side faces of the block 1, so as to be rigidly supported thereby.

For the purpose of securing the back to the base and also to enable the back to be disposed in varying planes most comfortable to the user, bolts I9 and 2D are provided at the end portions of the arms I8 and project through slots 2| and 22, respectively, provided therefor in the arms I 'I. The bolts I9 are slightly longer than the bolts 20 and provided with wing or thumb nuts 23. The slots ZI are substantially horizontal while the slots 22 are inclined, whereby upon shifting the back longitudinally of the stationary arms I8, the back will be caused to assume varying inclined positions in accordance with the extent of movement of theback; one inclined position of the back being depicted in dotted lines in Figure 1.

It will be apparent that by loosening the wing nuts, and shifting the seat toward the front or rear of the chair, the bolts I9 will be moved horizontally in their slots and the bolts 20 will ride along their inclined slots, whereby the seat will be tilted, or inclined, to the desired extent, following which the wing nuts are tightened, and the seat thereby held in its adjusted position.

Vertical adjustments of the seat to hold same at varying elevations is attained by removing the pin I5, moving the seat in accordance with the desired adjustment, and reinserting the pin in a selected one of the openings I4.

The block l, functions in a variety of ways, namely to support the center of the seat; to provide anchors for the arms I8 which latter likewise support the sides of the seat, and to provide supports for the arms I'I that support the back and to also provide a support for the post I2 and its bearing ball I0. T hus a most compact and rugged chair structure is provided and one which involves a minimum of parts and material.

From the foregoing it will be evident that the invention provides a chair which involves in its structure the use of a minimum of metallic ele1 ments; specifically four short bolts. At the same time the invention preserves all of the characteristics and functions of similar chairs in the prior art, wherein a relatively large amount of metal has been utilized in attaining equivalent functions. KK

While the use of wood is preferred and has so been described in the various primaryelements specified, nevertheless it is within the scope and spirit of the invention to employ other materials of either Various non-metallic naturesl or composition, and to otherwise make such other.V

changes as fall within the scope of the following claims. What is claimed is: Y l. A chair of the character described, including a base member, a standard carried bythe basemember, a seat member mounted on said standard, a pair of spaced rails carried by the under side of the seat member, a back member associated. with said seat member and having a pairof spaced arms cooperatingwith said rails, each of said arms being :formedY with a pair of spaced slots, one of said slots being substantially parallel to the plane Yof the seat' member while the other of said slots extends downwardly and forwardly at an angle to the first-named slot and the plane of the seat member, and means carried by each of said rails and extending through each of the slots of its cooperating arm, whereby to cause rearward tilting movement of the back member when the latter is moved in a direction away from .and having its upper free end disposed within said socket and against said bearing to thereby rotatably support said seat, a back member associated with said seat and having a forwardly extending part provided with a pair of spaced slots one of which is disposed in a substantially horizontal plane while the other of which extends forwardly and downwardly with respect to the first-named slot, and means carried by the seat and extending into said slots whereby to cause rearward tilting movement of the back member when the latter is moved in a direction away from said seat member.
